All of WorldServo’s motors are brushless AC servomotors with integrated encoders. Neodium-Iron-Boron magnetic material is used in all of the motors to attain high power density while maintaining a low cost per watt. These high power density motors help you increase throughput even when your available space for the motor is constrained.
The magnetic design of the motors includes skewed stators and/or rotors for minimum cogging torque and torque ripple.
Since the motors are brushless, the only parts with mechanical contact are the shaft bearings. The bearings used are oversized, single row, deep groove radial bearings with non-contact lubrication seals. The large ball bearings have diameter variations of less than 15 millionths of an inch, and the steel used is vacuum degassed and heat treated for maximum endurance. Thus, these motors are exceptionally reliable. Additionally, the SST’s true RMS torque limit feature protects the motor windings from overheating in the event of a mechanical jam or other high-current situation.
